Using force was inevitable with the way they structured their systems, and if we ever scrapped capitalism we would be in a similar boat. Noone who's advocating to do so is saying it so they can "work harder" or put forth more effort for the greater good. Its always talked about in terms of people working less and having more free time. So the question is how do you incentivize people to work hard or take on unwanted roles without the use of force. I think we have enough money and are advanced enough that we have options for that dilemma that those countries didn't have at their disposal.
If you think you can get a top 5 QB in the league it does make sense to trade up regardless.
Yes, it kicks the rebuild a year or two down the road, but that guy will help you 10-15 years (and with the cap increasing with a new cba "you can only compete with a QB on a rookie deal" is no longer a fact).
I have no idea if Tua is that guy, I'm just stating that there is an exception to "you do not trade up during a rebuild" and that is it.
